Release Summary

Kommander provides a command center for all your cloud native management needs in public Information as a Service (IaaS), on-premises, and edge environments. Kommander provides a multi-tenant experience to create, secure, and configure Kubernetes clusters and cloud native workloads. Kommander enables teams to unlock federated cost management across multiple clusters, whether they are a new Konvoy cluster or an existing 3rd party/DIY distribution installation.

Known issues

In Kommander version 1.3.2 and earlier, and Kommander version 1.4.0, the Kubecost cost analyzer requests a PVC of size 0.2Gi by default. This can cause issues with provisioners requiring a minimum storage size of 1Gi. This issue is fixed in Kommander version 1.3.3 and 1.4.1. Upgrading to these versions resolves this issue. Refer here for more information.

Breaking changes

Docker hub rate limiting

Docker Hub announced an update to image pull policies in August, 2020. The change results in the need to change cluster configurations to accommodate new account structures that enable image pull rate limiting.

Rate limiting happens on a per-pull basis regardless of whether the pulled image is owned by a paid user. This means D2iQ, as owner of most images used in Konvoy, does not have any influence as to whether your current address is rate-limited or not. Konvoy does not have a strict dependency on Docker Hub accounts or plans.

For more information on addressing this limit, see Docker hub rate limits.
